There are several little holes in the wall in San Francisco, that sell Chagall autographed prints for $35,000.00. Good artists sell shitloads, if they're dead. Look at David Bowie's last recordings. Dick Van Dyke played the lead in a movie about an actor who faked his death, in order for his art to sell. The trick was in collecting payment.
This year, yes, but if you move out of Portland soon enough, you won't have to pay it next year.
